APOD: Mars Red and Spica Blue

Mars will reach its brightest of this year this week. Mars looks so bright because it is so close to Earth. Spica, in the constellation Virgo, shines constantly as one of the brightest blue stars in the sky. Spica is blue in color, while Mars is reddish. Spica and Mars were photographed together toward the southeast in Sweden after sunset through old oak trees. I have seen Mars and Spica in the night sky, but it's always interesting to see a picture of the night sky from a different location.
